Initially, Paul Hayden Kirk's practice took on mainly residential projects and was characterized by historicist forms and details. Later he turned toward a more Modern approach to design, and many of his better known buildings from the early 1950s appear to rely heavily on the tenets and forms developed by International Style architects like Mies van der Rohe. However, where Mies preferred man-made materials for his structures, Kirk often favored natural stone, wood and glass.
